SANITARY cUsPInon.

Application led July 28,

My present invention pertains to sanitary cuspidors; and has for its general obJect the provision of a sanitary cuspidor which while simple and inexpensive in construction is highly eiiicient 1n the elimination of eX- pectorations and the like and is `therefore Figure 3 isa detail vertical section `here` inafter explicitly referred to.

2o Similar numerals of reference designate corresponding `parts in all views of the drawings. i

I show in Figure"1 a Hoor 1 which may be the floor of any apartment or any other place where it is desired to locate my novel cuspidor, and I also show in Figures 1 and 2 the cuspidor per se.

Among other elements my novel cuspi'dor comprises an uprightpipe 1x designed to be :zo connected with a source of Water supply and to maintain the head of water necessary for the maintenance of the cuspidor in a `thoroughly sanitary and wholesome state. The

said pipev 1x is providedat an intermediate` :1 5 point ot its length witha `lateral arm 2 `which at its inner end is merged into a vertically disposed terminal .3. ,i

The bowl of my novel cuspidor. is cast or molded or otherwise appropriately formed on the piperelatively arranged as shown; and it will be understood within the purview of `my invention, the bow] may be made of porcelain with vit-rified surfaces or of cast iron appropriately enameled or of any other material compatible with the purpose of the cuspidor. y

The bowl includes among other elements or features a concave-convex bottom 4, the essentially concave side of the said bottom 4 being provided with an upstanding rounded protuberance 5. This latter is provided with a central vertically disposed bore 6 in which is arranged the upstanding terminal 3 of the pi eand so that the surface of the rotu erance 5 is ilush with the upper en of 1927. Serial No. 208,997.

the terminal 3. The bowl also includes an upper rim portion 7 shouldered at 8 to bear on and be supported by the floor 1. In the said r-im 7 is an annular bore 8", the'said bore 8X being designed to receive water from the upper end of the upright pipe 1X, Figure, 3, and being in communication with inwardly and downwardly directed apertures 9' spaced apart `and adapted to jet I water against the concave bottom 4 and about the Vprotuberance 5. The body of the cuspidor also includes overflow openings 10 which are in communication with passages 11 dis osed under the bottom 4 and arranged to disc 'arge into a pendent waste conduit 12, the latter being designed to beconnected with a trap, not shown, in connection with a conventional or other suitable sewer pipe, also not shown,

. With a view to averting breakage when the bowl or body is formed of porcelain, a shoul der13, Figure 1, isvprovided adjacent to the apertures 9 and between said apertures 9 and the inner surface of the rim 7 Arranged in the bowl or body and about the base ot the protuberance 5 is a circular series of discharge `apertures 14. The said apertures 14 are vertically disposed in close proximity to the base of the said protuberance 5 and lead directly from the upper side of the Vbetteln 4 to the Waste conduit- 12. Manifestly under ordinary working conditions, the water jetted on the bottom 4 from the apertures 9 will pass together with eX- pectorations through the apertures 14 and to the waste conduit12,and hence there will be no liability of Hlth collectingr in the cuspidor bowl andabout the protuberance. In the event however that the apertures 14 are inadequate for anyV reason to carry off the waterand expectorations, any overilow will be taken care of by the overflow apertures 10 and the conduits l11 in communication therewith.

f It will be apparent from the foregoing that my novel cuspidor is provided through- Slt Again it will be appreciated that the entire surface of the cuspidor` is constantly flushed `with .clean water incident to the use of the cuspidor and this contributes materially to the sanitary character of the cuepidor.4 It wi'll `further be apparent that the' cuspidor utters but slight projection above the floor 1 porcelain it may be reinforced at the points `deeiiied necessary to reinforce, but the reinforcement per se is not oit my invention and I theretoreideeined it unncessary to illusi trate the saine.

I have explicitly described the preferred 'embodiment of' my invention in order to impart an exact understanding 01": the said `embodiment in all of ts details.

I do not desirei howeveigto be understood as limiting myself to theprecisev construction and configuration disclosed, my inventon being defined by my appended claiiiis'within the `scope otwhi'ch 'modifications may be made l without departure from my invention.

Having thus described the invention, what I" claim as new is l. In combination, aniupright pipe having a lateral arm terminating in an upright portion, and a Abowl havinga concave bote toni, andra 4central rounded protuberance Vin which is a vertical boie receiving the upright terminal Vportion oit the pipe arm, and alsohaviiig a series ot discharge aperg tures about and adjacent to the base of said and jet apertures iii communication with i rounded j'irotuberance, and further having a riiii with' anannular bore in communication witlithe upper end of said upright pipe 'j said `bore and directed toward theconcave 'bottoni and the base of the said protuber- 7 2.4 In combination, an upright pipe having ia lateral'arin terminating in an upright portion, and ir'bowl having a concave bottom, and a central rounded protuberance in which isa vertical bore receiving the upright terminal portion of the pipeA arm, and also having a series of discharge apertures about and adjacent to the base of said rounded I protuberaiice, and further having a rim with l an annular bore in vcommunication with the apertures inv communication with Vsaid bore upper end otsaid upright p ipe and jet anddirected toward the concave bottom and the base ot the said protuberance; the said bowl being equipped with a pendent waste conduit in coincidence with the said series of discharge apertures and heilig further pro` vfded iii its bottoin'adjacent to said rim with overflow apertures spaced apart, and conduits arranged under the bottom and extending between said overflow apertures and the said pendent waste conduit at points adjacent to the lower ends of theY saiddischarge apertures. j

3. A cuspidor bowl having a concave bottom, and` a rounded central protuberance thereon and means in said protuberance for conductingflush water tothe topot' the center of the protuberance and further having a pendent waste conduit, and discharge apertures through the bottom and arrangedv about and adjacent to the basent the said protuberance.

4. A cuspidor bowl having a concave botloin, and a` rounded Vcentral protuberance thereon and means in said protuberanceitor coiiducting flush water tothe topy of the center ot the protuberance and iiurtherhaving a pendent waste conduit, and discharge apertures through 'the bottoni andarranged about and adjacent to the base vof the said protuberaiiee; said bowl also having a riiii with a bore adapted to be connected lto a source of water supply and with jet-apei`- tures in coniniunication with Ysaid bore and directed toward the upper ysurface/oli` the bottoni and said protuberance, anda shoulder between the said' jet apertures and the inner side ot' the riin, and overflow apertures adjacent to the riiii and conduitsuiider the bottom and betweeiisaid overliow apertures and the pendent waste coiiduitat points adjacent rthe lower ends of the first named dscliarge apertures.

` A cuspidoii bowlV having a concave bottom, and 'a central roundedprotubeiance thereon' and abore through the centerJot said"protub'erance to a point.. at the top thereof and also having a pendentfwaste conduit, apertures about and adjacent to the barze ot 'the protuberaiace and coiii'iecting the upper side of the bottom with vsaid waste conduit', a= riin with abore and vjet apertures, overflow apertures through the bottoni adjacent to said rini,` and Iconduits between th'eoverfiow apertures and the pendent waste conduit.
